摘要

Critical current densities (J_c) and the irreversibility lines (ILs) of 7 melt-textured samples with different oxygen content (27.4 K < T_c < 92.4 K) were investigated. The values of J_c^ab decrease systematically with increasing oxygen deficiency. All the ILs shift to lower fields and temperatures with decreasing oxygen content. A crossover in the slope of log(H_irr) versus log(1 - T_irr/T_c) as well as pronounced changes in the shape and anisotropy of the ILs were observed.
